Lathyrus rotundifolius

Spring-Autumn · Outdoors

Water during dry periods

For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.

Spring-Winter · Planting

Tie branches to supports

This plant is usually grown up walls, trellis or fences. Since the plant cannot naturally support itself, it needs to be fixed to wires or other supports attached to the wall, trellis or fence.

The plant is most attractive when trained or it can become ugly with bare-stems. Use string or 'soft fixings' to attach the branches to the wires or supports on walls, trellis or fences.

Summer - early · Outdoors

Apply slow release fertiliser

Apply a slow release fertiliser which is spread around the root area of the plants soon after they have come into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Planting

Deadhead blooms during flowering season

Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.

The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.

Compost · Planting

Multi-purpose compost

Use a good quality peat-free multi-purpose compost when growing in pots and containers.
